#3171 of 3674 4WD Issue by jpmccr

Feb 27, 2008 (6:09 am)

Vehicle: 2001 Chevy Blazer LT, 4WD, 115,000 miles, V-6, Automatic. We went to my sister-in-laws in up state PA and they got snow. Went to put it in 4WD and the 4WD (4L) indicator light starts blinking. Checked 4H as well and it blinks as well. The front end would not lock in. A friend of the family said the blinking light indicated that there was a problem with the 4WD. Ok; is this something I can fix or is it something that is going to cost a ton money to fix???? I watched when my wife put in 4WD and the front wheels did not pull as they should. Any help/advice is greatly appreciated.

Please Help. I am trying to find the 3rd o2 sensor on my 95 Chevy Blazer. I found the one right before and after the cat, but can't find the one on the manifold. Been told there isn't one, then there is and it is the same sensor as the other two or it isn't. Haven't got a straight answer from anyone. If anyone can help that would be great. A pic would be awesome. Thanks in advance.

depends on how many wires you have on the sensor, and if the sensor is still there take it off and take it to your parts store for them to match it up

Try O2 sensors or EGR valve.

I need to know where on the truck the 3rd sensor is before I can take it off and bring it to a parts store.

Ok so a little history on the truck. I acquired it from a family member wrecked. I put over 800 in parts in it and did all the work myself. I also had to have some mechanicals done to it as fallows, new computer,EGR valve,4 wheel drive vacuum actuator and cable,intake hose, and some other stuff. The 4 wheel worked after replacing the actuator and the cable but the next day it no longer does. If the switch works it all the when i try to put it in 4hi the light on 4hi and 4lo just flash and go back into to hi. Other times nothing will happen when you push the button for 4hi. The same thing happens if i try to use 4lo. Could it just be the switch? I cant get my hands on a one to test my theory.... Any input would be great. Thanks guys

Yes I am having the same problems with my 97 Jimmy. We had to have the motor relaced because of the previous owner. It ran great with a 01 motor in it. We put on about 2k miles and then it started to stutter from stop to go. The idle is erratic and it through up like six codes. Five of which were Bank 1 Sensor 1 o2 sensor was shot. SO I replaced it. It helped for about a week now it's back to the same crap. WITH the P0300 code.I don't know what to do...if I can't fix it I am SCREWED!!! Ironically I moved up here to go to school to be a mechanic.. HA
